I am colorblind and autistic, and the context of favicons means nothing to me when the tabs are n a horizontal row. It’s so difficult. But with a vertical column of icons and rows of text, my God, it works so beautifully! Thank you so much! My only wish would be to have the option to also toggle it to pin it to the other side of the window (including to choose to have the icons be on the right side of the titles).
But as it is right now, bar none, this is the best tab implementation I’ve seen.
